How to clone a remote server?

Question

SSH

There is a hetzner server, I need to clone it, I remember I once used CloneZilla (for desktop PCs).
I uploaded the image, mounted it via KVM on a server, but after a reboot, there was no USB drive in the BIOS selection options, so this option disappeared.
What can be done? Upload iso to server and edit GRUB?
and after that, what kind of beast is DRBL, which is described here clonezilla.org/clonezilla-SE ?
Do I need it or not?

Answer 1

One option is to use the Mondo Rescue utility , which is specifically designed for server backup and cloning.

Answer 2

just rsync to a new server with the same OS, excluding system folders

Answer 3

as an example

rsync -arvxzP --exclude=/proc --exclude=/dev --exclude=/sys --exclude=/tmp [email protected]_host:/ /local/dir/

if ssh hangs on a non-standard port, for example, on 2222, then

rsync -arvxzP --exclude=/proc --exclude=/dev --exclude=/sys --exclude=/tmp -e "ssh -p2222" [email protected]_host:/ /local/dir/
